Fig. 1 is a side view of the'end portion of the gangway.

Fig. 2 is a horizontal sectional view showing'the end'of the gangwayexpanded at one side only.

Fig. 3 isarvertical section taken on the line 33 of Fig. 2. l

The gangway illustrated consists of the usual side rails 4e. flooring 5and longitudinal runners 6.

end sections 8 are hinged so as to turnout wardly about a vertical axisto any desired angle and thus afford more ready access to the gangway. V

In Figs. 2 and 3 of the drawings only one end section is shown turnedoutwardly. but it will be understood that, when the gangway is'in use,both end sections will preferably be turned outwardly. T .e flooring 5and runners 6: of'the gangway extend beyond the posts 7 and the spacebetween the end sections 8 and the flooring 55 (when the. end sectionsare opened out) isfilled by side platforms 9 hinged to the endsections8.

The platforms 9 may be built up of timber and of substantiallytriangular shape hinged at 10 to the bottom runners 1 1 of the The sidesof'the gangway terminate in posts or uprights 7 to which 1922. set-a1No. 569,726.

' end sections 8 so that. when the end sections 8 are collapsed, theplatforms9 fold up into avertical position side by side with the endsections 81n l1new1th the side rails 4.

The end sectrons 8 may be guided' by sultable means such as arcuate bars12. which.

are rigidly secured at one end to the runners 11 respectively. and workthrough guide apertures 1 in the runners 6. At one end the'bars 12 areprovided with perforated plates 1 for attachment to runners 11 and atthe other end limiting stops 13 are provided. The bars 12 are verticallyspaced,

as shown in Fig. 3, 'in order to avoid interference; hen the endsections 8' of the platform are swung outwardly (lower part ofFig. 2,and Fig. 3 at the left)this movement will be guided by the bars 12working in apertures 1 and limited by the end steps 13 when the lattercome against the runners .6,
